The BCL04 is available with one of two different lithium battery backups. Each would be well-suited to support a UPS in standard or edge data center applications.
- LMO Type Batteries–Lithium Manganese Oxide (LiMn2O4): Li-ion with manganese spinel has been around since 1983. In 1996, Moli Energy commercialized a Li-ion cell with lithium manganese oxide as cathode material. The architecture improves ion flow on the electrode, resulting in lower internal resistance and improved current handling. It also provides high thermal stability and enhanced safety, but the cycle and calendar life are limited.
- NMC Type Batteries-Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2): NMC is the battery of choice for power tools, e-bikes and other electric powertrains. The cathode combination is typically one-third nickel, one-third manganese and one-third cobalt, also known as 1-1-1. Cobalt stabilizes nickel but is expensive and in limited supply and so batteries may have reduced cobalt content and therefore some compromise in performance.
